THE BEST AND THE REST: REVISITING THE NORM OF NORMALITY OF INDIVIDUAL PERFORMANCE

We revisit a long‐held assumption in human resource management, organizational behavior, and industrial and organizational psychology that individual performance follows a Gaussian (normal) distribution. We conducted 5 studies involving 198 samples including 633,263 researchers, entertainers, politicians, and amateur and professional athletes. Results are remarkably consistent across industries, types of jobs, types of performance measures, and time frames and indicate that individual performance is not normally distributed—instead, it follows a Paretian (power law) distribution. Assuming normality of individual performance can lead to misspecified theories and misleading practices. Thus, our results have implications for all theories and applications that directly or indirectly address the performance of individual workers including performance measurement and management, utility analysis in preemployment testing and training and development, personnel selection, leadership, and the prediction of performance, among others.     

Unrecognized Posttraumatic Stress Disorder as a Treatment Barrier for a Gang-Involved Juvenile Offender

This study examines the case of GH, an 18-year-old Latino male participating in an employment-based delinquency intervention for gang-affiliated youth. Although postintervention measures revealed that GH showed gains on key outcomes (i.e., delinquency, employment), he experienced sporadic treatment setbacks (e.g., work absenteeism, fighting) that disrupted his progress. A comprehensive psychological assessment suggested that his aggressive, illegal behavior and difficulty maintaining employment could have been influenced by previously undiagnosed posttraumatic stress disorder (PTSD). Excerpts from counseling sessions illustrated how reactive aggression, hypervigilance, sleep disruptions, and emotional numbing could have interfered with treatment gains and ultimately contributed to GH's re-arrest. Implications for early, accurate identification of PTSD in delinquency interventions for gang youth are discussed.     

Concealing negative evaluations of a romantic partner's physical attractiveness

Two studies provided evidence that people hide their negative evaluations of their romantic partner's physical attractiveness. This pattern was found using self‐reports of concealment (Study 1) and a behavioral observation measure (Study 2). Participants who engaged in this deception also exhibited elevated speech disfluencies, which is a deception cue. Moderators of concealment were examined. Concealment was especially pronounced for participants high in care for the partner's welfare (Studies 1 and 2), low in commitment (Studies 1 and 2), and high in attractiveness ideals (Study 2). Results suggest that people use deception to regulate their romantic partner's feelings, but that long‐term orientation or desire to maintain closeness may curtail use of this strategy.     

DETERMINATION AND EVALUATION OF RATE MEASUREMENTS IN THE ANALYSIS OF SPACE MEDICAL DATA

Measures of rate of change and of rate of rate of change are developed for application to physiological and psychological data. Examples are given of the use of these measures with heart-rate data for comparisons within and between subjects. It is shown that the measures provide information over and above that offered by means and variances, and that the measures appropriately reflect the impact of external variables.     

ASSESSMENT OF STEREOTYPIC AND SELF-INJURIOUS BEHAVIOR AS ADJUNCTIVE RESPONSES

Certain responses of both humans and nonhumans appear to be maintained indirectly by intermittent reinforcement schedules and have been referred to collectively as adjunctive behavior. Although basic research has examined adjunctive behavior extensively, relatively few studies have been conducted with humans, particularly those with developmental disabilities who often engage in frequent and varied stereotypic behavior. This study assessed possible adjunctive characteristics of self-injurious and stereotypic behaviors using a multielement design containing two types of control conditions. Four subjects who engaged in both self-injurious behavior and stereotypy participated after variables maintaining their self-injury were identified via functional analyses. Each day, subjects were exposed to three 15-min sessions in random order: (a) noncontingent presentation of food on a fixed-time schedule (e.g., FT 30 s), (b) a massed-reinforcement (food) control, and (c) a no-reinforcement control. A variety of fixed-time schedules were examined during different experimental phases. Results of this preliminary study suggested that self-injury was not induced by intermittent reinforcement schedules, whereas the stereotypic behavior of some individuals showed characteristics of adjunctive behavior. The importance of research on adjunctive behavior and suggestions for future studies are discussed.
